Embodiment 1

[0049] The island-fixed superfine fiber of this embodiment includes island components and sea components, and the weight percentage of the two is 60%: 40%, wherein the island components are polyamide PA6, and the sea components are PE;

[0050] The preparation method of fixed island superfine fiber, comprises the following steps:

[0051] The island component is sliced ​​and dried. After drying, the water content of the slice is controlled at 100PPM. The dried sea component and the island component are put into their respective spinning storage tanks, and enter their respective screw extrusion through the feeding system. The machine is heated and melted, filtered, and then transported to the spinning box through the melt pipeline. The temperature control of the island components in each area is as follows:

[0052]

[0053] The spinning melt entering the spinning box first enters the respective metering pumps for metering, ensuring that the weight percentage of the island c...

Embodiment 2

[0057] The island-fixed superfine fiber of this embodiment includes island components and sea components, and the weight percentage of the two is 50%:50%, wherein the island components are polyamide PET, and the sea components are PE;

[0058] The preparation method of fixed island superfine fiber, comprises the following steps:

[0059] Dry the slices of the sea component and the island component. After drying, ensure that the water content of the slice is controlled at 30PPM. Put the dried sea component and the island component into their respective spinning storage tanks, and enter their respective spinning storage tanks through the feeding system. The advanced screw extruder is heated and melted, filtered, and then transported to the spinning box through the melt pipeline. The temperature control of the island components in each area is as follows:

[0060]

[0061] The spinning melt entering the spinning box is metered into the composite spinning assembly through its o...

Embodiment 3

[0064] The island-fixed superfine fiber of this embodiment includes island components and sea components, and the weight percentage of the two is 80%: 20%, wherein the island components are polyamide PA6, and the sea components are PS;

[0065] The preparation method of fixed island superfine fiber, comprises the following steps:

[0066] PA6 (polyamide) is used as the island component, and after drying to ensure that the water content of the slice is controlled at 80PPM, PS (polystyrene) is used as the sea component, which are respectively put into their respective storage tanks, and enter their respective screw extruders through the feeding system. The machine is heated and melted, filtered, and then transported to the spinning box through the melt pipeline. The temperature control of the island components in each area is as follows:

[0067]

[0068] The spinning melt entering the spinning box is metered into the composite spinning assembly through its own metering pump...

Abstract

The invention relates to figured island superfine fiber, figured island superfine fiber synthetic leather base cloth, suede leather for clothes, smooth synthetic leather for clothes and a production method of the fiber, the base cloth, the suede leather and the smooth synthetic leather and belongs to the technical field of synthetic leather and production method of the synthetic leather. The production method of the figured island superfine fiber mainly comprises the steps of 1), performing slice drying and fusion; 2), conducting composite spinning; 3), applying oil and dropping a bucket; 4), performing drafting and crimping; and 5) drying and cutting off the fiber. The figured island superfine fiber synthetic leather base cloth, the suede leather for clothes and the smooth synthetic leather for clothes can be produced through the follow-up processing of the figured island superfine fiber. A prepared synthetic leather product has excellent mechanical property, dyeing property and color fastness, is more suitable for synthetic leather of suede or synthetic leather for clothes, which is prepared by surface making, roller coating and surface printing deep processing based on the suede leather, and product application of the leather, and the product is high in durability, strong in color fastness, convenient to cut, fashionable in product design, moisture permeable, vapor permeable, fine and smooth in sensing of suede, and good in writing effect.

Description

technical field [0001] The invention relates to Dingdao superfine fiber, Dingdao superfine fiber synthetic leather base cloth, suede leather for clothing, smooth synthetic leather for clothing and a manufacturing method thereof, and belongs to the technical field of synthetic leather and the manufacturing method thereof. Background technique [0002] Microfibers for synthetic leather are divided into fixed-island type and indeterminate-island type, and synthetic leather based on non-fixed-island microfibers has developed rapidly in the world in recent years, especially in China's synthetic leather industry. The product system focuses on the development of synthetic leather products based on extractable non-stationary superfine fibers. The product technology and product applications are highly homogeneous, and the scale is extremely serious, which greatly restricts the technological upgrading and application field expansion of the synthetic leather industry. With the expansio...
